Cold Water Shock

While it can be tempting to take a cooling dip in the sea or a lake on a hot day, it’s important to remember that the water might still be dangerously cold. 

When open water is 15°C or lower, it is considered dangerous for cold water shock. Cold water shock is an involuntary condition that occurs when someone is suddenly immersed in cold water. It can happen to anyone in any type of open water, causing you to temporarily lose control of your breathing and ability to swim, which can lead to drowning. 

Reduce your chances of experiencing cold water shock by following this advice:

1 – If you’re going for a swim, enter the water slowly so your body has time to adjust to the cold

2 – Always go with a friend or group so there is someone around to phone 999 if you get into trouble

3 – If possible, wear a wetsuit and take a float and a whistle to help you if you get into trouble in the water 

4 – If you think you are experiencing cold water shock, #FloatToLive. Float on your back with your ears under the water and get control of your breathing. Move your arms and legs to help you stay afloat and don’t worry if your legs sink, everybody floats differently. One you feel calmer, shout for help, use your whistle or swim to safety if you can.
